Renesas Electronics ISL3330IAZ-T7A Line Transceiver, 20-Pin SSOP

The Renesas ISL333 SERIES are BiCMOS interface ICs that are user configured as either a single RS-422/RS-485 differential transceiver, or as a dual (2 Tx, 2 Rx) RS-232 transceiver. Both RS-232/RS-485 modes feature loopback and shutdown functions. The loopback mode internally connects the Tx outputs to the corresponding Rx input, which facilitates the implementation of board level self test functions.
